TBZ500 THERMOSTAT AT A GLANCE

This thermostat is compatible with most HVAC systems, including the following:

• 24VAC systems Note: requires both the 24VAC R and C (“common”) wires unless battery powered.

• Standard gas/oil/electric heating systems

- 1 stage heating and cooling

- 2 stage heating and cooling

• Heat Pump systems:

- 1 stage heating and cooling

- 2 stage heating and cooling

- 2nd or 3rd stage Auxiliary heating (heat strips)

• Do NOT use for systems with line voltage controls (120/240VAC) The thermostat can either be powered by batteries or

24VAC.

Battery Powered Operation

The thermostat can be powered by four AA Alkaline batteries. The thermostat will operate for approximately two years on four

AA Alkaline batteries depending on the frequency of user operations and backlight operation. Always use Alkaline batteries and

replace all four at the same time with NEW batteries.

Z-Wave Operation when Battery Powered

Important Note: If the thermostat is installed on a Z-Wave network, while it is battery powered, it does not work as a Z-Wave

repeater.

24VAC Powered Operation

Powering the thermostat with 24VAC power requires both the C wire (24VAC common wire - typically blue)

and the R wire (24VAC hot wire - typically Red). If the C wire is not available, then batteries are required.

Note! If the thermostat is powered from 24VAC, do not install batteries!

Z-Wave Operation when 24VAC powered

If the thermostat is installed on a Z-Wave network while it is 24VAC powered, it operates as an always-on Z-Wave repeater.

R vs RC and RH Connections:

Single Transformer HVAC Systems.

Typical modern central HVAC installations have a integrated heating and cooling system with a single 24VAC transformer. For

these systems, there is only one 24VAC “R” wire and it can connect to either the RC or RH terminal on the thermostat. The

thermostat is supplied with an RC-RH jumper installed. Do not remove the jumper for common transformer HVAC systems. Connect the wires as marked from the HVAC

system to the corresponding terminals on

the thermostat back.

*C wire (24VAC common) may not be

present. If not, batteries must be installed.

Heat - Cool Delta Sets the minimum separation between heating and cooling setpoints. Note:

Attempts to lower cooling setpoint below the heating setpoint will PUSH the

heating setpoint down to maintain this separation. The same applies to setting

the heating setpoint above the cooling setpoint, it will PUSH the cooling set-

point up to maintain the setpoint delta separation

Backlight and Button Operation

The thermostat backlight is normally set to go out after 10

seconds of no button presses to conserve battery power. If

the backlight is o, the rst button press of any button will

only turn on the backlight. Once the backlight is on, the

buttons function normally.

SETTING THE SYSTEM MODE

System Modes

• O: System is o. No heating or cooling will come on. If system was on, it will turn o immediately.

• Heat: Only heating will occur.

• Cool: Only cooling will occur.

• Auto: Heating or cooling will come on according to the heating and cooling setpoints. The system will

automatically switch between heating and cooling modes as needed to maintain the setpoints.

• Special Heat Pump Mode: Emergency Heat.

• Heat-E: An additional system mode, “Heat-E” for Emergency Heat will be displayed if the HVAC System Type is set to Heat

Pump. If there is a compressor failure with the Heat Pump system, setting the mode to Emergency Heat will allow the

supplemental Aux Heat to come on rst whenever there is a call for heating. It also disables the compressor output to

prevent further damage to the HVAC system.

Caution! Emergency Heat should only be used for emergencies until the HVAC system can be repaired. Running the system in

Emergency Heat mode is commonly the most expensive mode since only the electric heat strips are being used instead of the

more ecient heat pump compressor.
